Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607840, here are decompositions:

19 + 8607821 = 8607840
37 + 8607803 = 8607840
71 + 8607769 = 8607840
103 + 8607737 = 8607840
107 + 8607733 = 8607840
127 + 8607713 = 8607840
151 + 8607689 = 8607840
167 + 8607673 = 8607840

Showing the first eight; more decompositions exist.
